Solution Overview
Problem
Conventional image pickup apparatuses face issues with the mechanical and electrical connection between the handle unit and the main unit, leading to potential breakage of electrical contacts, inconvenience in wire handling, increased size due to external wires, and degradation of audio signals due to noise interference.
Innovation Solution
The design incorporates a handle unit with a resilient member between the handle-side connector and the fixing member, allowing for secure and flexible electrical connection without exposed wires, and includes an audio signal processor to prevent signal degradation, using a handle-side connector and main unit-side connector for reliable and noise-resistant signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical contacts are exposed externally for connection between handle unit and main unit, then mechanical mounting is firm and secure, but wire handling is inconvenient and apparatus size increases
Solution Approach 1:
The patent replaces the conventional mechanical wire connection system with an electromagnetic field-based wireless communication system. The handle unit and main unit exchange data and control signals wirelessly through electromagnetic waves, eliminating the need for physical electrical contacts and wires. This substitution resolves the contradiction by maintaining reliable communication while completely removing wire handling complexity.
Solution Approach 2:
The patent extracts and removes the electrical contact components and wiring from the handle unit structure. By taking out the wired connection system entirely and replacing it with wireless communication antennas and communication circuits, the design eliminates the problematic external wires while maintaining functional connectivity between the handle unit and main unit.
2Productivity
If electrical contacts are positioned for signal transmission, then operation signals can be transmitted, but audio signals may be affected by noise and signal quality degrades
Solution Approach 1:
The patent replaces the electrical contact-based signal transmission system with a wireless communication system that uses electromagnetic waves for data transmission. This substitution eliminates the electrical interference and noise problems that affected audio signals through shared electrical pathways, as wireless communication operates on a completely different physical principle that does not suffer from ground loops or electrical interference.
Solution Approach 2:
The patent introduces wireless electromagnetic waves as an intermediary medium for signal transmission between the handle unit and main unit. This intermediary replaces the direct electrical contact pathway that caused noise interference, allowing audio signals and other data to be transmitted without the electrical interference that plagued the wired system.
3Adaptability or versatility
If handle unit is made removable for transportability, then accommodatability improves, but electrical contacts may receive excessive force and break
Solution Approach 1:
The patent extracts and removes the vulnerable electrical contact components from the removable handle unit. By implementing wireless communication, the system eliminates the physical electrical contacts that would be subjected to mechanical stress during attachment and detachment operations, thereby preventing breakage while maintaining full functionality.
Solution Approach 2:
The patent replaces the mechanical electrical contact system with a wireless electromagnetic communication system. This substitution eliminates the mechanical vulnerability of electrical contacts to excessive force during handle unit attachment and detachment, while maintaining reliable data and control signal transmission between the removable handle unit and main unit.
